Do you ever write an expression in TestStand with a bunch of parenthesis () and get lost halfway through trying to figure out which pairs are open and which are closed. Well, I do. Every Day. And I spend accumulated hours a week just trying to keep track of which ) goes with which (. If I'm lucky I can look for a little red item in the expression, or click on the check expression checkbox, but when I have a 'only runtime evaluatable' expression I'm out of luck (which is rather often) ). Some languages/editors have a parenthesis matching, where the ) your cursor is on causes the matching ( to get bold or flash. Others start coloring each pair a different color, so it's easy to see them all. Why can't TestStand do something like this????
